The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball ...

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be ...

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
